2 Claims.

The invention relates to guns and more particularly to spring air gunshaving removable shooting barrels and magazine barrels associatedtherewith, and the invention consists, first, in the peculiarconstruction of the sights for the gun barrel; second, in theconstruction of the removable shooting barrel; third, in the means forlocking said shooting barrel in position and for simultaneouslycontrolling the closure for the shot opening in a magazine barrel, andfurther in various details of construction as hereinafter set forth.

In the drawings:

Figure 1 is an elevation of the gun;

Figure 2 is an enlarged sectional elevation showing the construction ofthe sights for the barrel and also the locking means for the removableshooting barrel;

Figure 3 is a longitudinal section through a false barrel and shootingbarrel;

Figure 4 is a perspective view showing the interlocking portions of thefalse barrel and shooting barrel;

Figure 5 is a perspective view showing a portion of the gun barrel withthe rear sight removed therefrom;

Figure 6 is a cross section substantially on line 6 6 of Figure 3;

Figure 7 is a rear end elevation of the sight.

Figure 8 is an end elevation of the false barrel with the true barrelremoved.

Sights for gun barrels are generally formed by a bead member at theforward end thereof and a perforated plate at the rear end. Itfrequently happens that in shooting, light shining on the perforatedplate and into the aperture therein and also on the bead will interferewith proper sighting. With the present invention, I have cured thisdefect by surrounding both the bead and the apertured plate with tubesof suiiicient length to shield the same from side lights. I have alsoprovided means for removably mounting the rear sight tube upon thebarrel and for holding the same in proper alignment therewith. As shown,A is the stock, B the false barrel, C the frame, and D the pivoted leverfor use in compressing Athe spring which actuates the air plunger. Asthe specific construction of spring pressed plunger and actuatingmechanism therefor forms no part of the present invention, I deem itunnecessary to further describe or illustrate the same.

My improved sights include a forward sight E which projects upward fromthe false barrel D and provided with a bead portion E', also a rearsight F which is formed with an aperture F' therethrough through whichthe bead E is sighted. The member F is preferably formed of a sheetmetal cup which is inserted within a tube G being welded or otherwisesecured therein at a point midway between the ends of said tube. Thetube G is secured to the barrel B by means of a tongue G at its forwardend which engages a struck up socket B on the barrel. At the rear endof. the tube G is a projecting ear H which is fashioned to t against thetop of the barrel to which it is secured by a screw I passing throughthe frame C and into the stock A. Between these forward and rear pointsof attachment is a saddle J which is preferably formed by an upwardlyprojecting portion of a spring abutment K secured within the frame. Thusthe saddle J which ts about the tube G will properly align said tubewhile the tongue G', ear I-I and screw I will secure the same inposition.

HeretoforeI guns have been provided with detachable shooting barrelssuch as L which are detachably positioned within the false barrel Dwhile the space within the latter barrel surrounding the shooting barrelis utilized for forming a magazine or shot reservoir. The presentconstruction includes this feature but I have devised a novel means oflocking the shooting barrel in position which also cooperates to form aclosure for the' feed opening into the magazine. As shown, the barrel Lis provided at its rear end with a tapered portion L which fits withinthe abutment M for the plunger (not shown). A guide N surrounds theb-arrel L adjacent to the abutment and serves to direct the shot into achannel N vfrom which they passI successively through an aperture N2into the barrel L. At the forward end of the barrel L is a cap member Owhich is formed of a cupped sheet metal blank having its body portion Odrawn inward to a smaller diameter leaving a return bent iiange O2. Thecenter of the cap is perforated with an inwardly extending flange O3which fits about the shooting barrel L and is attached thereto. The bodyportion O has a cut away portion O4 for registration with a shot feedaperture P in the false barrel in one position of rotative adjustment.This body portion also has struck out therefrom a lug O5 which serves asa guide for inserting the cap in the false barrel and also as a lock forretaining it in position. Cooperating with the cap member O and lug O5thereof is a reinforcement member fitting within the false barrel B andthis member is formed as a part of the sight member E previously de-Wigwam scribed. Thus as shown, the sight member E is formed as anupwardly projecting ange on a cylindrical member E2 which extends partway around within the false barrel B, leaving a gap which forms anentrance channel E3 for the lug O5. The portion E2 is also cut away atE4 to permit the turning 'of the cap O after the lug O5 has passedthrough the channel P3 and the edges E5 and E6 of this cut away portionform shoulders for respectively holding the cap against longitudinal orfurther rotative movement.

With the construction just described, when the barrel L is insertedwithin the false barrel B, its inner end L' will engage the aperture inthe abutment M and the lug O5 on the cap O will l enter the channel E3.The cap and barrel are moved inward until the lug O5 passes beyond theshoulder E5, after which the cap may be adjusted rotatively. This formsin effect a bayonet lock which holds the shooting barrel from accidentaldisplacement. It also serves the function of a valve or closure for theshot feed aperture P as in one position of rotative adjustment the cui"laway portion O4 is in registration with this aperture to permit ofintroduction of shot, while in the locked position the aperture P isclosed by an imperforate portion of the body O.

To protect the forward or bead sight from confusing side lights, a tubeis arranged to surround the same. As shown in Figs. 4 and 6, this tube Qis formed from sheet metal blank with laterally extending segmentalanges Q on opposite sides thereof which are welded or otherwise securedto the false barrel.

WhatI claim as my invention is:

1. The combination with a gun barrel provided with a spring abutmenttherein, the end of said abutment extending upward through a slot in thebarrel and fashioned to form a saddle, of a rear sight formed of a tubemounted above said barrel and provided with a centrally perforated diskarranged therein intermediate the ends thereof, said tube being securedto said barrel and resting upon the saddle at the upper end of saidspring abutment.

2. The combination with a gun barrel and stock, of a spring abutmentwithin said barrel having its upper end projecting through a slottherein fashioned to form a saddle, a rear sight comprising a tubemounted on said barrel and resting upon and guided by said saddle, theforward end of said tube having a tongue for engaging a struck upbearing on said barrel and the rear end of said tube being secured tosaid stock and an apertured disk secured within said tube intermediatethe ends thereof.
